Rain will be the main mode of precipitation today and tomorrow but some snow appears like it will make an appearance Thursday morning before dawn.

This Afternoon: Mostly Cloudy, Scattered Showers

Highs: Around 60 | Wind: S 4-8 m.p.h.

Tonight: Mostly Cloudy, Mild, Showers Likely

Lows: 55-58 | Wind: SW to NW 4-8 m.p.h.

Wednesday: Mostly Cloudy, Rain Likely, Cooler

Highs: Mid 50s | Wind: N 10-20 m.p.h.

A cold front lies to the west and ahead of it the region is experiencing scattered showers and mild temperatures around the 60 degree mark. Showers will continue to be in the forecast overnight with lows falling into the mid to upper 50s. The wind will shift tomorrow morning as the front moves to the east of D.C. This will allow for some cooler air to start making its way into the region with highs in the mid 50s tomorrow around Noon, falling into the lower 50s and upper 40s by the afternoon hours. Rain will be likely through the morning and continue to be possible through the afternoon.

Now for the biggest changes... The main energy from a trough currently moving through the Plains states will push into our region Wednesday night into Thursday morning. As this happens, an area of low pressure is expected to develop off the Eastern Shore and move northeast into the Atlantic. It appears enough cold air will get wrapped into this low that precipitation behind the low will change into snow before coming to an end Thursday around sunrise. There is the potential for some measurable snowfall, though it looks like it will be light and mainly only accumulating on grassy areas. Areas such as Loudoun and Frederick Counties and points west will have the greatest chance for measurable snowfall, but there is still the chance for a few slick spots in Montgomery, Fairfax and even the District itself. The time period for snow appears to be around Midnight to 4am Thursday morning. The sun may be breaking out across the region for the morning commute. We will have much more on this system today on the web as well as tonight on ABC 7 news at 5, 6 and 11pm.
